After a brutal, bloody Continental War against the ArchDemon of the Northern Province—the First Supreme Leader of the Beneath Heaven Society—the White Skull Clan barely survived. The war wiped them out. But in the end, Megumi struck down the First Supreme Leader herself, ending the war.

Victory came at a steep price.

Megumi bled out on the battlefield, her body broken, her mind heavy with regret. Their so-called triumph was nothing but a pyrrhic victory. Her clan was in ruins. The people she loved—gone. And as her vision faded, she cursed fate itself.

But fate wasn’t done with her.

She wakes up—seventeen again.

The same faces surround her. The callous, power-hungry members of the White Skull Clan. Her loyal and beautiful maid. Her caring elder brother. Her wise, dominating master. They're all just as she remembered. But this time, she’s not the naive fox teenager she once was.

She’s a regressor now.

And the youngest Kitsune of the White Skull Clan. Years of blood, pain, and hard-earned experience burn in her soul. She knows who will betray her. Who will die? Who must die? Who schemes? Who should be saved? And she knows exactly who nearly destroyed her world.

The ArchDemon still lives.

So, are the other Supreme Leaders.

This time, she’ll tear them apart.
